通过以下代码,您可以查看您的iPhone配置文件(常规/沉默)
,这里是代码
By the following code you can check your iPhone Profile ( Regular/Silent) and here is the code
CFStringRef state;
UInt32 propertySize = sizeof(CFStringRef);
AudioSessionInitialize(NULL, NULL, NULL, NULL);
AudioSessionGetProperty(kAudioSessionProperty_AudioRoute, &propertySize, &state);
if(CFStringGetLength(state) == 0) {
//SILENT
NSLog(@"Silent switch is on");
//create vibrate
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
//this 2 line below use to play audio even in silent/vibrator mode too
UInt32 audioCategory = kAudioSessionCategory_MediaPlayback;
AudioSessionSetProperty( kAudioSessionProperty_AudioCategory, sizeof(UInt32), &audioCategory);
}
else {
//NOT SILENT
NSLog(@"Silent switch is off");
}
关于此错误
error: expected identifier before '\x786f7073'
只需在每个类头文件中写下以下行
Just write below line in every class header file
#import <AudioToolbox/AudioToolbox.h>
